Catherine, did you know that when solving a Linear Equation, lines could either be vertical or horizontal?
Really Sarah? How do you know?
Why don't you come over and I'll show you!
Okay, let's go!
For example, lets solve this equation x < -3
x < -3
Yeah, Next, you try and solve Since x < -3 is basically 1 x -3 the answer would be -3 x = -3 Good Job! So now... if we had a graph, we'd plot that point on -3 on the "x" axis with a dotted line and shade everything below that point with a vertical line.
